I have a 120 ltr tank which I would like to start dry dose with Doff sequestered iron plant tonic and potassium nitrate. The iron comes in 15g pack, the back of the Doff sequestered iron plant tonic reads:
Fertiliser declaration:
Magnesium 10.0% (6.0Mg)
Iron 2.00%
Manganese 3.00%

I have use a calculator and know that I need to dose the potassium 1/4 tsp 3x per week, but I'm have troube working out the iron.

Also:
Can accidentally I overdose and hurt my fishies?
Can I add the both at the same time?

I have 2 questions about this. I am going to be having a heavily planted 10g tank eventually, but it will start off lightly planted until it grows in.

1.) Should I hold off or reduce the amount of EI dosing until the plants grow in more? Or should I go for the normal full dose to allow them to grow in quicker?

2.) According to this calculator (found from reddit's planted tank helpful guides section) it is recommending more of each nutrient than in this guide. Any clarification on this? For a 10g here is what it is recommending.

Due to the nature and philosophy of EI, time of day is not important. That said, I run my auto-doser at 6 am so that the nutrients are well mixed throughout the water for when the daytime lights come on at noon. I don't think it makes much of a difference though.

I'm dosing with EI method
3x Macros {Weekly}
3x Micros {Weekly}
Please tell me at what time I should dose 'Macros' &
what time I should dose 'Micros'

I haven't checked my CO2 levels in over a year. Just eye balled the bubble rate and watch the fish. The plants will grow and choke up the whole tank in about 2-3 months if I don't do heavy pruning. Haven't used any of my dry ferts either. Just what the fish supply.

^^ I guess it's back to the good old drop checker method..

Has anyone seen data showing the range of ppm of CO2 in water exposed to room air? Without knowing that, the de-gas method for measuring CO2 isn't accurate at all. A 1pH drop caused by CO2 means the ppm of CO2 went up by a factor of 10. But, if you don't know where it started you don't know what to multiply by 10 to get the ppm of CO2. People assume it will start at 3 ppm, but I haven't seen the data to prove that.

How effective is the de-gas method at measuring co2?

Been useing this method for sometime now 50% WC on Sundays, Nutrient dosing is done following the water change.
Su, Tu, Th: 1 tsp KNO3, 1/8 tsp KH2PO4, 1/4 tsp K2SO4
M, W, F: 10 ml Plantex/iron from a stock solution of 2 tbsp in 500ml water. Since then i have rescaped my tank to mostly anubis from a stocked tank of stems/root feeders an moss, questiin is should i cut back on any of the ferts? Not seeing any algae or anything so i guess i would be doing it to be a cheapskate lol anyway what do u guys think?

This is my tank now.
